TCG Rulings

Mentions in Other Rulings

Previously Official Rulings

These TCG rulings were issued by Upper Deck Entertainment and have since been deemed unofficial by Konami.[1] They were previously considered official and can still be correct, as long as they follow the official gameplay rules, or unless Konami has issued a ruling that says otherwise.

If your opponent activates "Amazoness Archers" when your selected Level 7 Spellcaster-Type monster attacks, only the Level 7 Spellcaster-Type monster can attack because of "Diffusion Wave-Motion"'s effect, so your other monsters do not attack, but the -500 ATK effect of "Amazoness Archers" is still applied to all of your monsters.

After you activate "Diffusion Wave-Motion", if all monsters on your opponent's side of the field are destroyed (with "Raigeki", etc.) then your selected Level 7 Spellcaster-Type monster can attack your opponent's Life Points directly.

You can activate "Injection Fairy Lily"'s effect when she is attacked by a Level 7 Spellcaster-Type monster selected with "Diffusion Wave-Motion" because her effect is applied during damage calculation.
